Application

Surface preparation

The material and processing temperature shall be between 18 °C and 25 °C.
Make sure the mold or master model is clean, dry, dust and grease free.
If mold or master-model surface is porous, it must be properly sealed prior applying the release agent.
Wax-based release agents are recommended. For further information regarding Sika release agent consult the corresponding Product Data Sheet.

Application

The fabric must be suitable for the use of epoxy resins.
For laminates glass fibres with binding twill are better than binding cloth because of its better suppleness.

 

SikaBiresin® L100 is applied to the selected fiber fabric (e.g. glass fiber mats) using a brush or hand roller.
The reinforcing fibers are laid in layers "wet on wet". The fibers must be impregnated with the resin without air entrapments. Entrapped air is expelled from the inside to the outside.
If the surface needs to be further laminated or bonded, it is recommended to use a peel ply.
It is recommended to lay a balanced laminate to avoid deformation during demolding.
Further post curing of the demolded part can improve the final mechanical properties.
Depending on the geometry and weight of the part, it is recommended to use a conformer while post curing.

STORAGE CONDITIONS

Both components must be stored at temperature between 15 °C and 25 °C in original unopened containers.
